Ms. Puck, 43, has been hired as director of strategic brand development for the fast-growing grocery store chain owned by Milwaukee-based Roundy's Inc.

“It's the next step in my career,” Ms. Puck said. “I've loved the store since it opened downtown. I'm an avid shopper. They're growing and I really believe in the brand. It's something I couldn't pass up. I get to focus on work I love — public relations, social media, marketing and partnerships.”

Earlier this week, the chain opened another store on the North Side, on Ashland Avenue. It's the 23rd Mariano's.
